WATER COOLER.

Application filed June so, 1927. Serial in. 202,545. 7

This invention relates to improvements in water coolers, and has for an object the proof clay, and water on the inside thereof tends 10 to moisten the clay, at least an osmosis action takes place, and this in conjunction with air permits a rapid evaporation,result 1ng in a cooling of the olla and hence a cooling of'the water within the olla. However, the

water maycontain some minute organisms, and it is a known fact that air contains germs of all forms. It has been found that the average olla which contains water becomes sour within a short period of time, possibly three weeks, if the water is not used up.

Furthermore the periphery of the ollaa ssumes a mouldy appearance, which 1s due in part to the presence of algae. In certain cases and in certain localities small worms may grow, eventually reaching the interior of the olla, rendering the Water unfit for use. When this occurs it is necessary that the olla be returned to the water company andthe exterior surface of the olla is ground to remove the algae, mould, dust and the like" therefrom. After an olla been ground several times it is rendered unfit for use as the wall thereof would be" too thin. The chief difliculty seems to be that the olla sur-. face is not s'utficiently protected and while a small amount of algae or mould or duston the periphery thereof might not in any manner injure the water therein, yet the appearance of algae on the olla 1s not favorable to 40 a user thereof.. This is particularly true when the olla are placed in factories.

With the idea of overcoming the faults above enumerated, my invention has for an object the provision of novel means which may be utilized in conjunction with the olla to prevent, in a measure, the olla from'becoming as quickly contaminatedv with algae, mould and the like, yet preserving a distinct air flow around the olla to the end that the water therein is chilled.

- Another object contemplates the provision of means whereby the container for the water maintains at all times a pleasing appearance.

Other objects will appear as the specification proceeds, and with such objects in view, the invention consists inthe novel and useful provision, formation, construction, association and relative arrangement of parts, members and features all as shown in certain embodiments in the accompanying drawing, described generally and more particularly pointed out in the claims. I

In the drawing:

Fig. 1 is an elevation of an embodiment of the invention; 4

Fig. 2 is a vertical sectional view of one form of the invention;

Fig. 3 is a plan view, partly in section of the embodiment of the invention shown in I i w Fig. 4: is a partially vertical sectional view of a modified form of my invention; and,

Fig. 5 is a'further fra mentary vertical sectional view of a modi cation of the invention.

Corresponding parts in the different figures are designated by the same referencecharacters. I

Referring now with particularity to the drawing, I have designated the improved m vention in the form shown in Figs. 1 to 3 inclusive by A, and in Figs. 4 and 5 by B and C respectively.

In the form A, a is the olla and bimeans adapted to surround the periphery of the olla and in part spaced therefrom.- The olla a is indicated'in Fig. 2 in dotted lines at 1, and, as will be ,seen, comprises a container provided with an enlarged neck portion 2.- In addition the olla has a faucet 3zadj acent the base thereof. Ordinarily a rubber gasket is inserted within the mbuth of the neck 2 of the olla and the neck portion of a demijohn 4.- is placed within said neck of the olla and bears against the rubber gasket. This will, of course, maintain the demijohn inan inverted position as'illustrated in Fig. 1, so that the contents or at least partof the contents of said demijohn will be received within the olla.

of air between the said means I) and the periphery of the olla. The means 6 includes an annulus having a side wall 6 provided with corrugated end portions Tand 8. In addition the side wall 6 is provided with one or more perforations 9. These corrugations act as ing with the olla. and yet allow a circulation a means for'spacing the Wall 6 from the periphery of the olla as shown at Fig. 2. The ends of said'member b may be overlapped as shown at 10 and spotwelded, or otherwise secured. I likewise provide a cover 11, constituting a part of the means I) and inthe present instance the cover substantially conforms in outline to the curvature of the upper end of the olla. This cover is provided with a rim.

12'and' with a tapered Wall 13. This tapered wall'portion, as shown, is substantially a hollow cone in cross section, with that portion of said wall 13 surrounding the annular open,-

ing thereof beaded at 14. This wall 13 is pro- .vided with one or more perforations" 15.

- This body portion is designated as e and the periphery is substantially straight sided, as indicated at 16 with ends of said sidewall formed with inwardly directed flanges 17 and 18. These flanges are annular in form and may be beaded as shown at 19 to lend rigidity A and strength thereto. The side wall may be provided with one or more perforations 20 located above the flange 18 and the flange 17 may be provided with one or more perforations 21. The cover 11, which will fit upon this member a, is provided with perforations 15. Thus when the olla is confined within the member a, with the cover in place, air may circulate through perforations 15, 20 and 21. Attention is directed to the fact that the mem- "ber c is. provided with a slot 22, so that the faucet 3 may be projected therethrough. This construction is necessary because the spigot or faucet 3 is usually within the olla and it is intended that the members either I) or 0, should be placed thereover so as to surround the olla without the necessity of removing the said spigot or faucet.

The form of the device depicted at Fig. 5 includes a member d adapted to spacedly suropenings.

In testimony whereof, I have signed my roundthe olla, and a cover 23. In this conthe member (1 with inwardly directed pe- I ripheral grooves. rected flanges formed by grooving thememberd, act to space the-greaterv area of said member from the olla. Such flanges may be perforated if desired. The cover is substantially an annulus formed with a depending rim portion. It is intended that the form C should be provided with perforations lying between the two'inwardly directed flanges 24, so that circulation of air against the periphery of the olla may be effected.

Any one of the devices asshown in the drawing would be simple of construction and is a protection for the olla as well as any These said inwardly di' water contained therein. The said members cations and variations'may be made in practising theinvention in departure from the partcular showing of the drawing without departing from the true spirit of the invention.

Having thus disclosed my invention, ll claim an desire to secure Letters Patent:

1. In a device adapted to surround an olla to prevent direct air contact therewith, comprising an annulus, and means at ends of said annulus adapted to uniformly space said annulus from the periphery of said olla.

2. In a device adapted to surround an olla to prevent direct air contact therewith, comprising an annular metal member provided with inwardly directed fluted end portions adapted to space the said annulus substantially evenly from the body of the olla.

3. In a device adapted to surround an olla to prevent direct air contact therewith, comprising an annulus, and means at ends, of said annulus adapted to uniformly space said annulus from the periphery'of said olla, said 10 annulus being formed with air circulation name to this specification. 1
